Saraswati Flumen
Saraswati Flumen is a river system of liquid methane and ethane on Saturn's moon Titan. It flows for 360 km before discharging into Ontario Lacus near Titan's south pole in a river delta on the lake's western shore. Its bankfull discharge is estimated to be 40–50,000 m3/s but its regular flow is estimated to be 10–2,000 m3/s. Compared to Karesos Flumen and Hubur Flumen, the two other major rivers that drain into the Ontario Lacus which both originate in mountains, the Saraswati Flumen has a much flatter gradient. The Saraswati Flumen is unlike most rivers on Titan including the more well known Vid Flumina in that it has a river delta. Furthermore, its delta is double-lobed, suggesting that the river switched courses over tens to hundreds of thousands of years to build both lobes. The main lobe is around 97 km2 in area while the secondary lobe is around 50 km2. It is hypothesized to be a suspended load-dominated river.
